GEMENTING APPARATUS.

Patented May 10, 1921.

Application filed December 17, 1918. Serial No. 267,190.

To (r71 whom it may concern:

Be it known that I, J OHN Coscnovn, a citizen of the United States, residing at Medford, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Cementing Apparatus, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

My invention relates to apparatus for the application of cement, being especially useful in connection with the cementing of the uppers of tennis shoes for the attachment of the foxing.

In work of the character indicated above, the cement which. secures thezffoxing to the upper must be applied in a band, .the edge of which toward the top ofthe slideshould be uniform and symmetrical with relation to the shoe bottom, so that it shall not project at any point beyond the foxing strip and thus deface the upper. An object of my invention is to shield the work effectively, as the upper at the foxing line, against the overrunning of cement. This I accomplish by the employment of a movable cementapplying member and a member situated beside it and arranged to define the line between the coated and uncoated areas, the last-named member extending through substantially the full length of the path of movement of the applying member. By

placing this member or gage in close prox-' imity to the brush, or other member which applies the cement, it may be caused to limit the application of cement in this direction. Preferably, I employ as a gage a disk rotatably mounted and having a thin edge for contact with the surface of the work being cemented. The gage is shown herein as supported on a bracket projecting from the frame of the apparatus, and on this bracket at the opposite side of the applying'member from the gage is preferably mounted a work-rest, which in cementing shoes for foxings contacts with the shoe bottom.

Another object of the invention is to operate the movable applying member effectively. I attain this by connecting to the carrier for the applying member at a plurality of points means for actuating it. The

brush or other suitable applying member is thereby driven in a plurality .of directions, which may be so related as to cause it to sweep over the work, rise therefrom and return clear of the work for a fresh stroke.

I have illustrated the applying member as passage through, which cement is fed to a passage in the carrier of the applying mem- In connection with the following description of a particular embodiment of the invention illustrated by the accompanying drawing, other objects will appear.

In this drawing,

Figure 1 is a partial side elevation of my improved apparatus, with portions in section;

Fig. 2 is an enlarged sectional detail on the hue 22 of Fig. 1 and Fig. 3 is a perspective view of a bottom-rest and gage line with their supporting bracket.

Upon a suitable frame 10 is mounted a cement tank 12, and journaled near ,the bottom of this tank is a horizontal shaft 14 projecting through an opening 16 in the tank wall. The shaft 14 is rotated through gearing 18 from a main shaft 20, ournaled in the frame below the tank and driven from a convenient source of power by a belt gnot shown) operating over a pulley 22.

utside the tank the shaft 14 is surrounded by an eccentric sleeve 24 spaced from it to furnish an intermediate passage 26. The connection between the shaft and sleeve is preferable through a block 28 pinned to the shaft and sleeve and being of less width than the passage, so that openings are left at each side to permit the flow of cement. Partly within the tank and partly in the passage 26, the shaft 14 carries a worm 30 by which the cement is advanced outwardly through the passage.

Supported upon the eccentric is a carrier member 32, at the end of which farthest from the tank is a downward angular extension 34 containing a vertical socket to receive a brush holder 36, which is fixed in the socket by a set screw 38. The holder has an inclined end 40 provided at one side 'with a socket, in which may be placed a brush or other applying member 42 held by a thumb, screw it threaded through the outer wall of the socket. The passage 26 through the eccentric sleeve is continued at r 46 through the extension 34 and the brush holder, and has at its lower end a nozzle 48 opening at its side in close proximlty to the brush 42. To control the flow of cement through the passage, the passage 46 in the brush holder has a valve 50 held normally closed by a spring 52 connecting an arm 54 fast on the valve stem with a bracket 56 rising from the brush carrier. Since both the valve arm and the bracket 56 move to gether with the brush in its applying stroke, this causes no variation in the tension of the spring. To allow the operator to open the valve to permit cement to flow through the nozzle to the brush, there is pivoted on the floor below the apparatus a treadle 58 joined to the arm 5% by a connecting rod 60. The depression of the treadle rotates the valve against the tension of the spring 52 to open it. Since the throw of the eccentric 24 is short, the relative movement between the valve, which is moved with the carrier by the eccentric, and the treadle, pivoted to a relatively fixed point, is slight and has no Ill effect on its operation.

In addition to the vertical movement imparted to the brush carrier by the eccentric 24, there is a horizontal component to cause points at the applying surface of the brush to describe ellipses. This horizontal movement is produced by an actuat 1ng member consisting of a crank pin 62 pro ect1ng from the end of the shaft 20 and extending between the divided ends 64, 64: of an arm 66 depending from the carrier 32. The resulting movement of the brush is shown by the dot and dash elliptical line in Fig. 2 of the drawings. In its rearward movement from the operator, it passes in contact with the work along the line indicated at a. It then rises as shown at 7). returning out of contact with the work at c and descending at (I for the succeeding stroke.

Fixed to the side of the frame 10 below the end of the shaft 20 carrying the crank pin is a bracket 68 having an upwardly extending angular end} 70 adjacent to the brush holder. To this end 7 0 of the bracket is fixed a U-shaped horizontal extension or yoke 72, between the arms of which extension the brush moves. On the outer arm is carried a gage member. This is preferably in the form of a disk 74 moi-ably mounted at 76 upon the extension arm. The arm is shown as inclined outwardly and upwardly from the brush, so that the reduced edge 7 8 of the disk is brought into close proximity with the outer side of the brush, yet leaving the latter with its holder and associated elements ample space for their movement. The diameter of the gage disk and its relation to the path of movement of the brush is such that said brush, during substantially its entire movement, is opposite the disk, the interposed gage thus limiting the flow of cement over the linetraced by its edge upon the upper. In a way formed in a lower horizontal surface of the bracket 68 is movably mounted a work-rest 82, adjustably secured in place by a thumb screw 84 extending through a slot in the gage arm and being threaded into the bracket. At the outer extremity of the work-rest is a vertical contact face 86, which is herein illustrated as parallel to the path of oscillation of the brush, and against which the bottom of the shoe being cemented is pressed by the operator to guide it in correct relation to the brush. To cause the applying edge 88 of the brush to rest uniformly against the curve of the upper to which the cement is to be applied, this edge is inclined, as indicated at 88, so that it approximately conforms to this curvature.

In using this apparatus, the tank 12 is supplied with cement, and power being applied to the pulley 22, the cement is forced from the tank by the worm 16 through the passage 26 and its continuation 46, and when the valve 50 is opened, this cement is delivered through the nozzle 48 against the side of the brush. The operator places the lasted upper which is to be cemented with its bottom against the face 86 of the workrest, with the edge 78 of the gage disk contacting with it to define the upper line of the foxing, and moves it beneath the oscillating brush 88, the applying edge of which extends transversely of the upper. This brush. as has already been pointed out, during its travel in one direction sweeps over the work. applying thereto cement from the nozzle 48, and then returns out of contact with the upper for another stroke. The cement is thus brushed out effectively, its passage beyond the line of the foxing being prevented by the interposition of the gage disk 74. The rotation of this disk allows the movement of the work under the brush with little resistance. To allow the relation ofthe gage disk to the brush to be altered. the yoke 72 may be attached-to the bracket by a screw 77 passing through a slot 79 in the inner arm of the yoke, while the yoke may be in sections joined by a screw 81 threaded into one section and extending through a slot 83 in the other. By the adjustment first mentioned the position of the disk with reference to the path of the brush may be altered, while by the second, the distance between the disk and brush may be changed and therefore the location of the edge of the band of cement applied.
